Discover SUMSUM, where innovation and collaboration thrive. With a strong focus on end-user centricity, quality, teamwork, and continuous learning, we deliver exceptional solutions that drive your success.
End user centricity
End user centricity is key at SUMSUM. It is our mission to co-create products that really matter and reduce the delivery gap.
Quality with capital Q. We take the time to elicit your needs and translate them to epics, features and user stories.
We love learning about anything that pushes companies to the edge: artificial intelligence, virtual and augmented reality, robotics, or even edge AI.
Our team thrives in agile environments where working together multi-disciplinarily and good communication are key.
We value ownership, where we strive to be impactful, lead with purpose, and proactively drive positive change in everything we do.
We believe in the power of collaboration and consciously creating an environment where we embrace failures as learning opportunities.
We foster a flat organization, where we believe in sharing, caring, and embracing change for collective growth. There's no "I" in team.
